Infusing asphalt with plastic could help roads last longer and resist cracking under heat

The plastic is already here and unfortunately we haven’t figured out a good way to get rid of it. So instead of polluting our oceans and landfills, why not use it for better roads? At least until we figure out a better solution.
So we shred it to tiny particles and that’s that? Hmm
It’s already shredding naturally. At least this process contains it for longer than it otherwise would, potentially reduces more shedding from tires, and gives it some purposeful existence while we come up with better ideas.
Better than just letting it rot somewhere, right? At least, that’s my take. Maybe it’s wrong, but it’s not the worst idea I’ve ever heard.
Mixing it with a binder, effectively embedding it into a semi buried rock a seems like a slightly safer option than letting it sit out in the sun to be broken down by UV.
Not sure there are any “safe” options tbh but I’d rather it serve some purpose if it’s just going to break down either way, for sure.
